Argh! I hate these casual invocations of evolutionary biology that are really self-serving fables. By numbers of individuals, diversity, and by mass, bacteria and blue-green algae make up most of the biological world. Multi-cellular life only appears dominant to you because that's who you eat and who you mate with. Evolution cares not a whit for smart, dumb, slow, fast, it only cares who has the most babies who live to make other babies. Making arguments for the virtues of entrepreneurs is fine, just don't try to dress them up as scientific truths, unless you actually can muster the evidence.
